As seismic waves travel through different mediums in the earth, the different mediums create different wave velocities. With geophones, the amplitude of the wave response can be measured at the surface and overlaid to create travel-time curves that tell what’s underneath.. Earthquake Mechanisms. Brittle Mechanical Model: “stick-slip”. Focal point: 3D point inside the lithosphere where the seismic event occurs. Epicenter: projection of focal point to the map surface . Part 1. Seismic Waves and Interior of the Earth. The behaviour of seismic waves in the different layers of the earth provides the most authentic evidence about the composition and structure of the earth. The different types of waves, generated during the occurrence of an earthquake, are generally divided into three broad categories: .

The exceptions are seismograms of deep focus earthquakes, which are not effective generators of surface waves, so that the body waves are more prominent. The dominance of surface waves on .
